Denitrification of recirculated aquaculture system effluents using fish sludge as primary substrate
Shamsaddini Negari, Mohammad (Master thesis, 2023)Recirculating Aquaculture System (RAS) is a technology in which water is reused after different biological and mechanical treatment steps in fish farming. RAS produces a nitrate rich water effluent containing approximately ... -
Energy optimization of biological wastewater treatment using rotating belt filters upstream BNR
Razafimanantsoa, Valeri Aristide (Doctoral thesis, 2020-04)Treatment of wastewater to acceptable permit standards requires energy, mostly as electricity. The typical energy demand for various wastewater treatment technologies vary from 0.30 to 1.50 kWh/m3 of treated water. For ... -
Investigating phosphate release from EBPR sludge and associated possibility of controlled struvite precipitation at SNJ wastewater treatment plant
Egeland, Mari (Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06)The main treatment stage at SNJ Wastewater Treatment Plant was recently upgraded from chemical treatment to mechanical-biological treatment with Enhanced Biological Phosphorous Removal (EBPR). The implementation of EBPR ... -
Investigation of Enhanced Biological Phosphorus Removal (EBPR) Process Performance at SNJ Wastewater Treatment Plant (IVAR)
Lilleland, Ayu Rahmi (Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06-15)This study has investigated the efficiency of phosphorus (P) removal and optimization the function of the Enhanced Biological Phosphorus Removal (EBPR) at SNJ (Sentralrenseanlegg Nord-Jæren), owned by IVAR (Interkommunalt ... -
Pilot-scale study to investigate the impact of rotating belt filter upstream of a MBR for nitrogen removal
Razafimanantsoa, Aristide Valeri; Adyasari, Dini; Sahu, Ashish K; Rusten, Bjørn; Bilstad, Torleiv; Ydstebø, Leif (Peer reviewed; Journal article, 2019-02)The goal of this study was to investigate what kind of impact the removal of particulate organic matter with 33μm rotating belt filter (RBF) (as a primary treatment) will have on the membrane bioreactor (MBR) performance. ... -
Struvite formation and dewaterability of digested wastewater sludge from IVAR - SNJ
Castillo, Ana (Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-15)Controlled struvite formation in digested sludge from IVARs main wastewater treatment plant “Sentralrenseanlegg Nord-Jæren (SNJ) was investigated as a way to improve the dewaterability of the sludge. Improving dewaterability ...
